The err_put_fd tag is only used once, so remove it to make the code more
readable.
I think it's a conventional style to put error handling in the bottom of
the function so that it could be reused. Indeed currently err_put_fd
has only one caller but IMHO it's only styling issues.
By the way it seems that this is not needed anymore if patch 9 is applied.
This is just to make patch 3 look clearer, if you insist on dropping it
I will drop it in the next revision.
Cheers,
Baokun
